For comparison's sake, Malaysia puts 500,000 vehicles on the road every year. In China, motor companies sold 13 million last year.
Sure it's a big country but how many 13 million can it take? I read that every day 60% of the oil output goes to "feeding" motor vehicles. And in return we get plenty of by-products.
If the recent natural disasters around the world are any indication then I say the future of this planet is bleak.
